The rack-bar 9 is carried bytwo arms 11 pivoted, at 12, to blocks 13 adapted to be secured to thecarriage by screws 14, mequivalent, and it will be seen that saidrack-bar may thus be raised vertiried cally out of engagement with theescape- "ment pinion 8 to permit free carriage move- GEORGE onAieIorAewjobn, ea; "or LT'AMPA, stoning Y I -TY1'E-WRITERAMAQHMEIiT, r

the preferred form of construction-I form the teeth ofthe rack-bar onone member of a plate 15 bent into channeled form, U

shaped in. cross section, as clearly shown in' Fig. Land the othermember 16of which is confined between the side flanges of a a horizontalportion of arod 18 having also a tion 19 and a supplemental horizontalportion. 20., The rod 18 is in pivotal connection. with a key-bar 21pivoted at 22 and main vertical porhaving a key 23-at the frontenduthereof,

and, t t/ Will be seen that, ifthe key23 be" depressed, the rod 18 israised, carrying-the roller 17 therewith, and releasing the rack barQiromthe pinion 8, the member 16 of i 17 in the movement of the I alsoprovidertwo-standards Bl upon the top of themachine fraine,.a11d in thetop of which is pivoted a toothed bar 25normally arranged at an angle tothe hori/anital portiongfl'ot 8, and'upon which it bears. and it willlie-seen that; if the key 2-3 be depressed, this bar 25- is moved on itspivots' 'intohorizontal,position approximately, simultanev ,with tlieelearaiiee of the rackbar 9 fron thepinion 8. v

Slidablealong the bar 25 .1s having, teeth adapted forengagement withthe same in adjusted positionagainst dow theplate-la beingthen earrie'dby the roller ar to hold said step at ward nioi einent. and, when thebar 25 is released as just described, the stop 20 the path of movementofthe arm 10 which strikes said stop and prevents further car- Y riagemovement by means of its spring; when the key 23 is released, therack-bar is again engaged with the pinion 8, the stop 26 drops out ofthe path of the arm 10, and.

normal operation of the machine may he enters resumedpwhen desired, thekey 23 may be quickly and lightly tapped to raise theraekbar out ofpinion engagement for an mstant, thus enabling the carriage to move arorresponding distance tor ea h of said" taps, this being in the eventof a desire to have the carriage feed more rapidly than by the normalescapement operation in writing.

To install my device, all that is necessary is to drill the holes andtap the same for the screws holding the standards 24, arm 10,

blocks 13, and the lug carrying the keylever pivot 22, remove theconventional rackbar, andsubstitute my plate 15 therefor, a suitableguiding hole being also provided, if required, through the frame of themachine, for the vertical portion 19 of the rod 18, and, when the partsare in place as shown, the device is ready for use.

It will be obvious that the stop 26 may be adjusted in any desiredposition, as for a column of figures, and it will also be obvious that Imay employ as many of the stops as are required or desired to suit thecharacter of the work being done on the typewriter; I may permit thecarriage to jump all the way from relr position to stop position or byshort jump; through delicatc taps on the key 23; I may then release thecarriage to jump to another stop, if two or more are used, in one or aplurality of jumps; and I may, after the last stop, operate the machinein the usual manner.

While I have shown the device as applied to :1 Remington typewritingmachine, I do not limit myself to this type, nor to any specific type,neither do I limit myself to,

the exact details shown and described, as

changes may be made thereover, either for the type of machineillustrated or for other types, my invention consisting, broadly, in theprovisionof an attachment for the purpose stated which may be quicklyand easily connected with a typewriter.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a typewriting machine comprising a frame, a carriage movablethereon, an escapement pinion, a rack bar engaging the same and aplurality of keys, a tabulating attachment consisting of a rigid armprojecting rearwardly from said carriage, a

toothed bar pivotally secured to the frame and normally held in anoblique position, a

stop adjustably locked to said toothed bar on its toothed edge, asupplemental key, and means operable by the depression of said key forsimultaneously lifting the rack bar from the escapement pinion andswinging the toothed bar on its pivots to a horizontal position to carrythe stop into the path of said harm, said rack bar and stopbeingreturned to normal position in the upward movement of thesupplemental key.

2. .In a typewriting machine, provided adjustably locked to the toothededge of said bar, a supplemental key, a lever therefor in detachableconnection with said frame, and means operable by said supplemental keyfor simultaneously lifting said rack bar from the pinion and swingingsaid toothed bar on its pivots to a horizontal position to carry thestop into the path of the rigid arm on the carriage.

3. In a typewriting machine comprising a frame, a carriage movablethereon, a plurality of keys, an escapement pinion, and a verticallymovable rack bar engaging said pinion, said rack bar being invertedU-shape, the front wall having a toothed lower edge, the lower edge ofthe rear wall being smooth, the front wall normally engaged by theescapement pinion, a tabulating attachment consisting of a rigid armprojecting rearwardly from the carriage, a bar pivotally mounted on thesaid frame, a supplemental key lever, a vertically disposed rodpivotally connected at its lower end to said lever and bent horizontallyadjacent its upper end forming an axle arm extending under the pivotallymounted bar, a grooved roller mounted on said axle arm, said rollersupporting the rear Wall of the rack bar, and an adjustable stop carriedby the pivotally mounted bar, whereby upward movement of the verticallydisposed rod by the key lever, will. disengage the front Wall of therack bar from the escapement pinion and simultaneously swing thepivotally mounted bar to a position to carry the stop thereon into thepath of the aforesaid rigid arm projecting from the carriage.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
